On this page you’ll find complete disassembly instructions for a HP Pavilion dv7 laptop.
This is my second guide for HP Pavilion dv7 laptop.
In this particular case I’m taking apart a HP Pavilion dv7-4177NR model.
I believe this guide should work for the all dv7-4000 series laptops.
READ THIS: I found that HP Pavilion dv7 laptops come in different body types. If your laptop doesn’t look like one shown in this guide, check out:
my first HP Pavilion dv7 disassembly guide
my third HP Pavilion dv7 disassembly guide (for dv7-6000 series)
my fourth HP Pavilion dv7 disassembly guide (for dv7-2000 and dv7-3000 series).
As you see this laptop has a cracked screen. My target is replacing the damaged screen but I’ll do a few extra steps and show how to disassemble the entire laptop.
It’s not easy to replace the LCD screen on this HP laptop. In order to do so it’s necessary remove the laptop palmrest assembly (STEPS 1-19), separate the display panel from the laptop body (STEP 20-25) and only after that disassemble the display and replace the screen (STEP 33-48).
Also, I show how to remove the laptop motherboard and access the cooling fan (STEPS 26-32) but it’s not necessary to go though these steps in order to replace the screen.
Make sure the laptop is turned off.
Unlock and remove the battery.
Loosen five screws securing the bottom hatch.
Lift up and remove the hatch.
Under the bottom hatch you can access the following laptop components:
- both memory modules ( I’ll leave them connected to the motherboard).
- wireless card.
- CMOS battery.
- hard drive.
HP Pavilion dv7 laptop has an opening for the second hard drive but in my laptop I had only one hard drive installed.
Remove screws securing the hard drive assembly.
Unplug the hard drive cable from the motherboard.
Lift up and remove the hard drive assembly.
Remove one screw securing the DVD drive.
Pull the DVD drive to the left to disconnect it from the motherboard.
Remove the DVD drive from the laptop.
Remove two screws securing the keyboard on the bottom of the laptop.
Slide the keyboard release button to the left.
This button located in the battery compartment, on the left side from the battery connector.
After that you should be able to lift up the upper side of the keyboard.
Move the keyboard towards the LCD screen so you can access the cable connector underneath.
In the following two steps I explain how to unlock the keyboard connector and release the cable.
Carefully lift up the left side of the connector retainer with your fingernail.
The retainer will open up at a 90 degree angle.
On this picture the connector is shown in the unlocked position.
Now you can pull the keyboard cable from the connector.
Remove the keyboard from the laptop.
Remove all marked screws from the bottom of the laptop.
UPDATE: Thanks to Just a Guy (comment 6):
On step 15 please see this image wait to remove screw with blue circle and SPECIALLY screw with yellow circle. Another note there are also screw ping circle to remove!
Remove yellow and blue ONLY on step 18 having laptop in SAME position of step 18 image. THIS IS IMPORTANT!!
So it why? Seeing step 24 image u can see that display hinges screw remaing are only 2! It leave it very weak and can damage screw plastic part near cooler.
Don’t forget to remove three screws in the DVD drive bay.
Remove two screws securing the palmrest assembly.
Disconnect the following cables:
- wireless card cable.
- touchpad cable.
- finger scanning device cable.
You unlock all three connectors using the same technique as for unlocking the keyboard connector.
Lift up the connector retainer.
Pull the cable from the connector.
Now you can start separating the palmrest assembly from the laptop bottom cover.
You’ll have to wiggle the palmrest in order to unlock hidden latches.
Remove the palmrest assembly.
On the bottom side of the palmrest assembly you can access the following components:
- power button board.
- finger scanning device.
Now we are going to separate the display panel from the laptop base.
First, we’ll release the wireless card antenna cables and then unplug the video cable.
Disconnect two antenna cables from the wireless card which is mounted on the bottom of the laptop.
Unroute both wireless card antenna cables.
Unplug the video cable connector from the motherboard.
Remove two screws securing the display hinges.
Lift up and separate the display assembly from the laptop base.
I will continue taking apart the display assembly and removing the screen in the step 33.
Laptop motherboard removal.
Remove two screws securing the motherboard.
Unplug the following cables (left to right):
- left speaker cable.
- USB board cable.
- right speaker cable.
Both speaker cables have a regular male-female connector type.
Unplug the male part from the female part. Do not pull by the wires.
Lift up the right side of the motherboard a little bit and unplug the DC jack cable from the motherboard.
Also, in order to remove the motherboard, it’s necessary to unplug the hard drive cable.
You’ll find this connector on the bottom side of the laptop close to the memory modules.
Start removing the motherboard from the bottom cover as it shown on the following picture.
Remove the motherboard.
The cooling fan assembly is mounted to the bottom side of the motherboard.
Yes, it’s necessary to remove the whole motherboard in order to remove and replace the fan.
The DC jack is mounted in the upper right corner of the laptop base cover.
The DC jack harness can be easily removed after you remove one screw securing the DC jack bracket.
LCD screen removal and replacement instructions.
As I mentioned before, in order to replace the screen it’s necessary to separate the display panel from the laptop base as it explained in steps 1-25.
You’ll find two screw covers located in the lower left and right corners of the screen bezel.
Remove both covers with a sharp object.
Remove two screws found under those covers.
Start separating the screen bezel from the display back cover. I’m using the guitar pick for that (you can use a piece of plastic).
Insert the guitar pick between the bezel and display back cover and move along the side. This will help you to unlock the hidden latches.
Also, the screen bezel is glued to the screen with sticky tape. You’ll have to apply some reasonable force to separate the bezel.
Continue removing the bezel on the upper part of the display assembly.
Lift up and remove the right hinge cover.
Lift up and remove the left hinge cover.
Remove the screen bezel.
Remove eight screws securing the LCD screen assembly to the display back cover.
Disconnect the cable from the web camera module.
Now you can separate the screen assembly from the display back cover.
Place the LCD screen face down on the table.
On the back side of the screen you can access the video cable and web camera cable. Both cables bundled into one harness.
Unglue the web camera cable from the back of the LCD screen.
Disconnect the video cable connector from the LCD screen.
Remove the LCD screen assembly.
Remove two screws securing the right hinge mounting bracket. Transfer this bracket to the new LCD screen.
Remove two more screws securing the left hinge mounting bracket. Transfer this bracket to the new LCD screen.
Now you can replace the damaged/failed LCD screen and assemble the laptop following this guide in the reverse direction.
The best way to find a new replacement LCD screen is searching by the model number from the original screen.
The model number printed on the back side of the screen. In my case this is N173O6-L02 Rev. C.
When you search for a new screen make sure the video connector on your new screen located in the same place as on the old screen.
